TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Mar. 12, 1912.

Application filed March 17, 1910. Serial No. 549,909.

To all whom it may concern:

Be it known that I, CARL F. LUNnnBERc, a citizen of the United States, residing in Hartford, in the'county of Hartford and State of Connecticut, have invented certain I new and useful Improvements in Type-VVriting Machines, of which the following is a tions, and therefore, permit the characters to be, enlarged in size. To these ends, the key has an indicator bar or shaft journaled to turn over therein, said bar having a num-- her or other sign on each of two or more of its sides.

In the accompanying drawings, Figure 1 is a perspective view of a key equipped with my invention and partly broken away to better show the construction. Fig. 2 is a part sectional View, showing the indicator shaft in normal position. Fig. 3 is a similar view, showing the indicator shaft -par-' tially rotated. Fig. 4 is a perspective view of the component parts of the key disassembled. Fig. 5 is a diagrammatic View showing the connection between the key and a denominationstop. Fig. 6 is a diagramtions.

matic plan view showing in the upper row a.

set of denomination keys, of which the first four are of ordinary construction, and the last sixare constructed in accordance with theinvention. Upon' these six keys the movable indicators are shown. Thesec- 0nd row illustrates the same six keys, the indicators having been rotated so that the keys may be used for different denominaper row, the ten keys and their stops are adapted for'denominat-ional work up to millions, with punctuation marks between the hundreds and thousands, and also between the hundreds of thousands and millions. In the lower row, the punctuation marks a're omitted and the capacity of the machine is increased to hundreds of millions. Fig. 7

When adjustedaccording to the up-' is a' detail perspective view of the indicator shaft, showing the other two side faces from those shown in the detail view in Fig. 4. I

The key is illustrated as mounted upon the usual lever 2 which is connected to a-rod- 3 having at its upper end a denomination stop .4 to-cooperate with a column stop 5 carried upon a rack or bar 6 mounted upon the usual carriage (not shown). The key comprises a base or seat '1 on which is mounted a cap 8 in the form of a ferrule, having ears 9 to catch under the seat. The cap has a rim 10 around its upper edge turned over upon a transparent cover or glass plate 11, superposed upon a shutter 12 having openings 13. The shutter rests upon an annular shoulder 14 formed in-a stationary ring or annular body or barrel 15 seated on the base 7 and inclosed within the cap 8, said 4 shutter having nibs l6 fitted into'recesses .17 in the upper edge of the ring to hold the shutter stationary.

The space between the shutter 12 and seat 7 constitutes a chamber within the key, in

which is located a character-bearing device comprising an indicator shaft 18 having a plurality of faced sides, upon which the characters are applied, difierent faces or sides bearing different characters. The opposite reduced ends 25 of said shaft or bar are rotatable in opposite elongated guideslots or bearings 19 formed in the walls of i the ring 15, and the shaft turns over in the key, on an axis parallel to the face. of the key. An indicator bar having more than crease in the number of designations for each key is obtained. Moreover, byarranging the shaft to turn over on an axis parallelwith the face of'the key, the characters on the shaft may be made larger than'practicable heretofore on character-bearing disks which rotated in plates parallel with the In the example shownin Figs. 2, 3 and 4,-

one face of the indicator b'earsthe characters 1 T, mean1ng one thousand, and another face'bears the characters 10 T, meaning ten thousand. The former characters, preferably, lie-at right angles tothe latter, so

two faces can be used, and consequent -in.-' 4

' 10 T to become hidden and 1 T to be brought into view. Fig. 7 shows the remaining two sides of the indicator, bearing characters corresponding to those used in the English monetary system. The shaft may be provided with-either more or less sides than the four indicated in the drawings, and the characters may be applied to all the faces or to a less number, as desired. The finger piece may project from either side or at the rear of the key, as is most convenient. Said shaft is yieldingly supported by a compres sion spring 22, resting on the seat 7, the ends of which spring are crossed, as at 23, to form a crotch or hearing for the indicator shaft, which is annularly grooved intermediate its ends, to form a neck, as at 24:, to

allow. the spring fingers to clasp and hold the shaft up.

One or another of the faces of the indicator is normally pressed up against the closed end of the cap by the spring 22, to

prevent accidental'rotation of the indicator shaft. The characters register with the openings 13 in the shutter. When the indicator is turned over to change :the key denomination, the uppermost face operates as a'cam against'the under surface of the shutter, to force the indicator downwardly in its slots 19, and opening 21, against the tension of, the spring 22, as shown in Fig. 3, during the first half of its quarter-revolution; the spring forcing the indicator back to normal os itibn, shown in Figs. 1 and 2, during the atterhalf of the quarter revolution.

The shoulders26 formed at the juncture of'the body of the indicator and its reduced ends contact with the opposite sides of the ring 15 to prevent endwise displacement of the indicator.

Variations may be resorted to within the scope of the invention, and portions of the mprovements may be used without others.
